Pipe connection structure

Abstract

The present invention relates to a pipe connection structure further comprising an auxiliary seal ring for improving sealing performance, which is disposed within a connector. The present invention provides a pipe connection structure for detachably connecting one end of one pipe serving as a male pipe to one end of another pipe with a connector formed thereon or coupled thereto by inserting the end of the male pipe into the connector. The connector includes a seal ring, a tension washer, a fixing ring, a push-button and a connection cap. The pipe connection structure further comprises an auxiliary sealing-ring groove formed in a portion of an inner surface of the connector which corresponds to the end of the male pipe inserted into the connector, and an auxiliary seal ring fitted into the auxiliary seal-ring groove, thereby preventing leakage of a fluid at a connected portion of the pipes. According to the present invention, since the auxiliary seal ring for complementing the conventional seal ring is additionally provided within the connector, there is an advantage in that complete sealing performance can be maintained even when fluids such as liquid and gas are carried.

What is claimed is:  
     
         1 . A pipe connection structure for detachably connecting one end of one pipe serving as a male pipe to one end of another pipe with a connector formed thereon or coupled thereto by inserting the end of the male pipe into the connector, said connector including a seal ring, a tension washer, a fixing ring, a push-button and a connection cap, comprising: 
 an auxiliary sealing-ring groove ( 11 ) formed in a portion of an inner surface of the connector ( 10 ) which corresponds to the end of the male pipe ( 14 ) inserted into the connector; and    an auxiliary seal ring ( 20 ) fitted into the auxiliary seal-ring groove ( 11 ), thereby preventing leakage of a fluid at a connected portion of the pipes.
